for my 2316 it seems that the stock plenum might be reaching it's limits as far as volume goes.....so, I either fabricate a larger common plenum, or go with individual throttle bodies such as TWM or Jenvey*
single plenum would be easiest, but the individual throttle bodies look better (IMG:style_emoticons/default/smile.gif) has anyone switched from one to the other on the same motor with everything else being the same??? *Jake Raby is the U.S. distributor of these.... |

Ya know you can tune your intake runner length in two ways....
One is to cut it to length. As the pulse is reflected up the intake runner, it hits the cut end and reverses direction... Now iffin you were, clever you could reverse the pulse where ever you wanted (in a system) by adding an anti-reversionary feature (cone) in the manifold- say below the MAF or MAP sensor. That sucka would act as a one-way valve and allow air to be sucked in and would reverse the pulse once it hit the AR feature...(See Feuling patents on AR exhaust) (IMG:http://www.914world.com/bbs2/html/emoticons/huh.gif) Now iffin you were brilliant, mebbe by taking a thin wall tube and placing it into the manifold near the ideal tuning point with the AR feaure on the trailing end would allow you to move the AR feature to locate the tuning point..... (IMG:http://www.914world.com/bbs2/html/emoticons/ohmy.gif) Since that tunes it for one RPM, moving it back and forth with a mechanism would tune your intake over the RPM range........
